Re: MMS doesn't work with Wi-Fi?

I believe SMS does not use the data network like Internet, email etc do, but rather a small channel on the voice network since the messages are such small blocks. So when on WiFi, the phone is probably unable to switch to that channel for the SMS. Just a semi-educated guess based on what I recall. Look up SMS for the technical details.
